In Prusa Slicer the support xy separation is in percentage, and the percentage means in relation to the perimeter/wall thickness.
Prusa Slicer xy separation
In Creality print 5 the xy separation in set in mm and default is 0.35mm.
Now when I have a wall thickness of 2mm which xy separation would you recommend? I read that 75% would be good, but this would be 1.5mm distance, what seems a lot to me?
